Okay, so we're asked to answer the question of why it makes sense to define full employment at when the unemployment equals the natural rate of unemployment.
00:10
So first of all, let's define the natural rate of unemployment.
00:14
So the natural rate of unemployment, we're going to re -view it as nru, is going to equal the structural unemployment plus are frictional.
00:28
And then the unemployment rate is going to be structural plus frictional plus our cyclical.
00:40
So for these two to be equal, what that's going to apply is, is that the cyclical is equal to zero.
00:50
And this is where we define our full employment.
00:54
So this is full employment.
01:03
So why does it make sense to use this definition instead of this alternative definition? which is when our unemployment rate is equal to zero.
01:14
Well, if our unemployment rate is equal to zero, and we set this at full employment, what that would mean is that there is no structural, no frictional, and there's no cyclical...
